Brian brings up an excellent point all Buyers need to be aware of; however, in this case the MLS only shows multiple entries for Unit B, which definitely has some square footage fluctuation amongst its historical listings and sources.
The current Active listing is Unit A and tax records do show it to be 1,763sf.
The property is Active and easy to with a Realtor. It is a probate sale although the listing agent states that court approval is not necessary. Your Realtor can obtain additional information and arrange to show the property to you.
